final def ##(): Int

Equivalent to x.hashCode except for boxed numeric types and null.
Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

a hash value consistent with ==

final def ==(arg0: Any): Boolean

xs
the elements to put in the array
returns
an array containing all elements from xs.
final def asInstanceOf[T0]: T0

Cast the receiver object to be of type T0.
Cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

the receiver object.

Exceptions thrown
ClassCastException if the receiver object is not an instance of the erasure of type T0.

def copy(src: AnyRef, srcPos: Int, dest: AnyRef, destPos: Int, length: Int): Unit

Copy one array to another. Equivalent to Java's System.arraycopy(src, srcPos, dest, destPos, length), except that this also works for polymorphic and boxed arrays.
Note that the passed-in dest array will be modified by this call.
src
the source array.
srcPos
starting position in the source array.

starting position in the destination array.

final def eq(arg0: AnyRef): Boolean

Tests whether the argument (arg0) is a reference to the receiver object (this).
Tests whether the argument (arg0) is a reference to the receiver object (this).
The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:
- It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
- For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
- null.eq(null) returns true.
When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).
returns
true if the argument is a reference to the receiver object; false otherwise.

def equals(arg0: Any): Boolean

implicit def fallbackCanBuildFrom[T](implicit m: DummyImplicit): CanBuildFrom[Array[_], T, ArraySeq[T]]

A builder factory that generates a generic array.
A builder factory that generates a generic array. Called instead of Array.newBuilder if the element type of an array does not have a class tag. Note that fallbackBuilder factory needs an implicit parameter (otherwise it would not be dominated in implicit search by Array.canBuildFrom). We make sure that implicit search is always successful.
